 ir long-term consequences, present a substantial global health burden. Wea
 rable prophylactic braces are an attractive potential solution to reduce t
 he incidence of joint injuries by limiting joint movements that are relate
 d to injury risk. Given human motion and ground reaction forces, we presen
 t a computational framework that enables the design of personalized braces
  by optimizing the distribution of microstructures and elasticity. As vari
 ed brace designs yield different reaction forces that influence kinematics
  and kinetics analysis outcomes, the optimization process is formulated as
  a differentiable end-to-end pipeline in which the design domain of micros
 tructure distribution is parameterized onto a neural network. The optimize
 d distribution of microstructures is obtained via a self-learning process 
 to determine the network coefficients according to a carefully designed se
 t of losses and the integrated biomechanical and physical analyses. Since 
 knees and ankles are the most commonly injured joints, we demonstrate the 
 effectiveness of our pipeline by designing, fabricating, and testing proph
 ylactic braces for the knee and ankle to prevent potentially harmful joint
  movements.\n\nRegistration Category: Full Access, Full Access Supporter\n
